Data Standards Browser (Browser) is a user interface for the CDISC Library. CDISC Library account holders can log into the Browser with their existing credentials. Upon logging in, users will be greeted by a landing page that allows access to available CDISC standards. The Browser content is represented visually by the same underlying linked metadata available through API.

With the Browser, CDISC Library users can:

• Select which standard to review in more detail by searching or traversing through its hierarchy;
• Provides clear relationship delineations across and within standards;
• Apply filters at the result level to further refine focus of search;
• Export content at the product level into supported file formats;
• Review draft contents prior to their publication;
• Download a diff report for comparing a versioned standard to its predecessor.
• Access QRS instrument's metadata and download an Excel export.

Usage Notes

Status
colour Yellow title Updated

• Browser session does not expire.
• Idle session does not consume bandwidth.
• Buttons have tooltips, a small "hover box" with information about the item being hovered overWhen using the search functionality (located top right), an asterisk can be used as a wildcard character. For example, to return all ADaM variables beginning with CRIT, enter CRIT* in the search box.
• Exports are available at the top level of each versioned standard.

Diff

• Diff report is downloadable through the Export button. For example, to download a diff report between SDTM CT Q1 2021 and its immediate predecessor, SDTM CT Q4 2020:
  • Select CT 2021 Q1 from the left navigation panel.
  • Select SDTM CT 2021-03-26 from the list of packages.
  • Click the Export button.
  • Select the Diff Report in Microsoft® Excel® (XLSX) option from the drop-down box.
• Depending on the browser setting, a diff report will either be automatically downloaded when it is ready; or, a dialog box to acknowledge a file download may be needed.
• Please note only diff reports of two successive versions are supported through the Browser. Use the API for downloading diff reports of skipped versions, such as SDTMIG v3.4 vs. SDTMIG v3.2 (skipping v3.3). Refer to Diff for technical details.

Limitations

• For Controlled Terminology, users can request exports at package level. These exports will contain all codelists of a package. CDISC is working toward enabling similar export for individual codelists. The Exports button for codelists is currently only a placeholder for future enhancement.For CDASHIG, users may experience UI issues when performing a search with this scope parameter: core : Recommended/Conditional. CDISC is working to resolve this defect.
  
• Value lists, such as those in ADaMIG and SDTMIG, are currently not displayed. This is only a display limitation. Value lists are available in exports, as well as through API endpoints. An example of value list is the valueList object in the response from this API query: /mdr/sdtmig/3-2/datasets/RELREC/variables/RELTYPE:

{
  "ordinal": "6",
  "name": "RELTYPE",
  ...
  "valueList": [
    "MANY",
    "ONE"
  ],
  ...
}
